- sArErY MItK- orrm nornna;

'Be it known thatI, LOUIS and State of New York, have invented new a "and useful Improvements in Safety Milk? Bottle Holders, of which the following .is a

I Specification.

' and the objectsof the same are to produce a milk bottle holder vwhich will not be locked by the insertionof anempty bottle but will be'when this bottle is exchanged for one that is fulhandto produce an attachment] which may be added so that the capacity of" i the device may be considerably amplified,

without necessitating any change'in or addi-'.

tion to the locking mechanism. This im-v 7 proved milk bottle holder is such as is ,lusuany put upalongside. a door, such as the kitchen door which opens'onto the back porch, or in some places itmay be putup'on, a post alongside the-Qfront gate, and the, millnnan making his early-morning rounds His supposed to remove yesterdaysjmilkf bottle which is nowjenipty andtvelean. and;

It .isfZwell' knownthatf malicious persons often helpjthemselves to ithe milk when so left, or" perhapsa. stray d Or a. in itsettorts'to get the lid off the bottle] 40;

cat may be attracted to the milk and will tip it over on theporchQ Always there are flies and other insects, and it is well known "that in the time between the delivery?" of the milk and its acceptance by the housewife, itis exposed to whatever may befall.

Provision hastherefore been made by means i of milk bottle holders, and one class ofthe'se devices is looked by the closlngof the door o while another class has a lock of its own.

My invention belongs-to the last-named 1 class, but it contains,. special Tmeans for adapting it to those occasions when-an ex tra supply of milk is erence being had to the acc'ornpan'yingdrawings where1n: I

while the tooth 10 is engaged by the bolt" 11 of the lock, and therefore the cover can I not be again raised to remove the bottle until l0. fThe result is that when the latter descends it passes the beveled tip -of the bolt and pushes the same outward against the force of the spring, but after the tooth-haspassed the bolt the latter is projected by the "spring and therefore the plunger is looked in its depressed position and thecover 3 is locked closed on the neck of the'bottle Q. This bolt forms part of a lock broadly -indicated by the numeral 15, and in the present be out of sight and out of reach. Now

beneath the device above described is a second cup-shaped casing 12 over which moves an' inverted cup-shaped cover 13, the latter carriedby a p lungerflt movablethrough a '55 are normally raised by a, spring 19 which 7 may well inclos ethe plunger and rest upon the guide, its upper-end engaginga' pin 21 as" seen. The plunger extends upward through ,a hole 14 in the bottom of the casing 2 and is 'detachably connected at its upper end in any appropriate manner with the mechanism above described. [As here's'hown I guide 17 as seen, and'this plungerand cover have illustrated its upper end as threaded as at 15 to engage a threaded socket 18 formed plunger-within its guides.

WVhile the p I Mounted on andprefer-j ably secured to the porch floor Pdirectly in the platform 8, and therefore when the plunger is raisedits threaded end may be screwed into said socket by rotating the The casing 12 and cover 13 may be of sheet metal, and the parts should be so proportioned that when the platform 8 rises to raise the main cover 3 and expose the device for the daily use, the cover 13 will rise off the casing 12 to expose the lower receptacle for extraordinary use. Now when the housewife desires an extra supply of milk, she puts some extra bottles \vithin'thelower casingand a note in the bottle inthe uppe'rcasing. finds this note and'fills the order? He puts the usual bottle Q'into the upperca'sing as abovedescribed and the additional bottle B into thelower casing, and the'weight of the upper bottle depresses the platform, while the downwardly movingplatform depresses the plunger 16 and'closes thecover lid-over the casinglQ, thereby protecting the bottles B as well as the single bottle Q. At other times theplunger 16 is disconnected'from the -socket 18 in the platform 8 andout of use, andyet it is not much in theway. In

fact the device maybe sold, with or without this attachment, according as theho'usewife desires. If purchased with the attachment, the latter may be put into useonlywhenit is necessary, and for this purpose the lower end ofthe plunger 16 may be deta-chably connected -'-with'the" cover 13' as by across pin 20." When this pin iswithdrawn the cover comes 0d and" the plunger may beentirely removed from its guides 17 "and taken into the house, the-other pin 21-and thef'spring 19; being of coursefc'arried with it. I- have said the casing 12 is attached to the porch, but it may not be-necessary to attach it as it is" sufficient if it-rests thereonfbecause when-the cover l3' comes "downover it the casing and'the bottles thereinare prevented frornr'emoval or interference. Thus the at taclnne'ntamplifies the capacity of the defvic'e according to the capacity of the attachment. The main device may be adapted for a quart'bottle or'fora*pintb.ottle-, and the attachment for several additional bottles.

The 'attachment'itself could be made insizes, as when used by a boardmg h'ouseor a-smallsized hotel. The parts are allof' the desired materials and proportions, and I have not gone into working details, as they maybe left to the manufacturer.
